IPC: H02K19/26
Filed: 1980-10-23
Abstract: PURPOSE:To prevent leakage flux and coercive force of a permanent magnet from reducing, by placing the permanent magnet by shifting it in the circumferential direction against a magnetic pole of a field coil and by separating a magnetic path in the stator side of the permanent magnet from that of a stator of the field coil. CONSTITUTION:In a fixed field system equipped with field coils wound on stator iron cores and permanent magnets performing initial excitation, the permanent magnets 7 are installed at the central position of an N pole iron core 11N and an S pole iron core 11S. The permanent magnets 7 are fixed to auxiliary yokes 12 forming magnetic paths on the stator side for said permanent magnet 7, and the auxiliary yokes 12 are fixed to the S pole iron cores 11S via non-magnetic material pieces 13. With such constitution, the auxiliary yokes 12 forming the stator side magnetic paths for the permanent magnets 7 and the iron cores 11N, 11S and a main yoke 10 forming the stator side magnetic paths for the field coils 6 are magnetically separated by the non-magnetic material pieces 13. Thus, since the permanent magnets 7 are between the iron cores 11N, 11S, and has independent magnetic paths, it is possible to reliably generate an initial excitation voltage.

Title: Device for preventing copying of confidential document
Inventor: ISHII RIE
IPC: G06T7/00
Filed: 1994-06-29
Abstract: PURPOSE:To prevent the copying of a confidential document by simple software by extracting a character string from a read original image, and at the time of detecting the overlap of the character part, judging that the original image is a confidential document. CONSTITUTION:When a picture reader binarizes the image of an original by a prescribed threshold, rectangles which has black dots continue for a certain length are continuously included, these rectangles are recognized as a character. When another area disconnecting a regulated rectangular string appears, whether character strings exist before and after a non-character string or not is used as a decision reference for the existence of a confidential mark. An area of a symbol A is judged as the overlap of a confidential mark expressing a confidential original to a character string and an area of a symbol B is judged as a graphic or a photograph. When a rectangle area larger than each of continued rectangles exists inn a character string, the existence of overlap to the character part is judged and copying is inhibited.
